Stefan Eichenberger bb1bdc72dd rtc: snvs: Allow a time difference on clock register read ... [ Upstream commit 0462681e207ccc44778a77b3297af728b1cf5b9f ] On an iMX6ULL the following message appears when a wakealarm is set: echo 0 > /sys/class/rtc/rtc1/wakealarm rtc rtc1: Timeout trying to get valid LPSRT Counter read This does not always happen but is reproducible quite often (7 out of 10 times). The problem appears because the iMX6ULL is not able to read the registers within one 32kHz clock cycle which is the base clock of the RTC. Therefore, this patch allows a difference of up to 320 cycles (10ms). 10ms was chosen to be big enough even on systems with less cpu power (e.g. iMX6ULL). According to the reference manual a difference is fine: - If the two consecutive reads are similar, the value is correct. The values have to be similar, not equal.
